Reilly Transparent Penetrating 

Reilly Transparent Penetrating Creosote is a new and dis- 
tinct product possessing maximum preservative properties. Se- 
t» vere scientific tests have shown it to be the greatest forward 
step made in the field of wood preservation. It provides positive pro- 
tection against the deterioration of lumber from insect attack and rot. 
Wood treated with Reilly Transparent Penetrating Creosote is 
dry, not oily, and can be painted. 

Preserve Against Deterioration 

Insects and decay yearly destroy more than $300,000,000* worth 
of lumber already in service in the United States. The continued rav- 
ages of termites and decay in buildings causing this large economic 
waste show that the lumber used in the construction of the buildings 
was not protected against the attack of wood-destroying organisms. As 
the quantity of lumber used has been steadily increasing, and the quan- 
tity available steadily decreasing, the protection of lumber against 
deterioration has become an economic problem which has required and 
received scientific attention. 

The failure to use preserved lumber in buildings in the past can be 
attributed to three causes: (a) the failure of the individual as well as 
the community to realize that termites have spread to all parts of the 
country; (b) the difficulty experienced heretofore in obtaining a mate- 
rial, scientifically prepared and easily applied, to protect lumber against 
insect attack and rot; (c) the inability of individuals as well as com- 
munities to cope with this problem. 

Scientifically Proven 

The development of Reilly Transparent Penetrating Creo- 
sote is the result of years of scientific research by The Reilly Labora- 
tories in co-operation with the Termite Investigations Committee. Inten- 
sive research on wood preservatives has been conducted for a number 
of years by The Reilly Laboratories. For four years the Termite In- 
vestigations Committee of California has studied all phases of the 
protection of lumber against termites.

Exhaustive tests under conditions far more rigorous than any en- 
countered in actual service have demonstrated that Reilly Transpar- 
ent Penetrating Creosote preserves the wood against both decay 
and wood-destroying insects. 

The studies by the Termite Investigations Committee, a group of 
scientists, have proven that Reilly Transparent Penetrating Creo- 
sote affords complete protection against termites. 

Reilly Transparent Penetrating Creosote is offered to the 
public because it was proven, by independent scientists working in the 
interest of the public, to protect lumber against termite attack, thus 
guarding against the collapse of buildings due to the weakening of 
supporting timbers by these insects. 

Easily Applied 

The rapidity with which Reilly Transparent Penetrating Creo- 
sote penetrates deeply into the wood is another of its remarkable 
characteristics; the ease with which lumber can be treated is an out- 
standing development in the field of wood preservation. Certain woods, 
as larches, hemlock, firs, and white oak, because of their refractory 
nature are ordinarily difficult to treat under pressure; for these woods 
it is recommended that Reilly Transparent Penetrating Creosote 
be applied under pressure. Other woods, as southern pine, cypress, sap 
cedar, red oak, ashes, hickory, maple, gums, and cherries can be suc- 
cessfully treated by immersion. 


Wood treated with Reilly Transparent Penetrating Creosote 
remains practically unchanged in color, and its surface is not oily. 
Immediately after treatment the lumber is ready for use, and sixty 
days after it is in place the lumber can be painted. Before applying 
the first coat of paint the wood must be thoroughly brushed with a 
wire brush. Also, the preservative treatment being to a degree a filler, 
a saving of paint results because less is required to cover a given 


Reilly Transparent Penetrating Creosote contains no water. 
For this reason the preservative can be used to treat seasoned lumber 
without affecting its moisture content. It can also be used on glued 
stock without affecting the strength of the glued joints; thus it can be 
applied to completed window frames and sashes, doors, etc.

Lumber treated with Reilly Transparent Penetrating Creo- 
sote does not decay nor is it attacked by termites or other insects. The 
use of Reilly Transparent Penetrating Creosote preserved lum- 
ber for sub-flooring and basement timbers, for fences and porches, for 
window frames and exterior trimming, and for roof construction ob- 
viates future replacements. Outdoor furniture is preserved against 
decay if wood treated with Reilly Transparent Penetrating Creo- 
sote is used in its construction. Wooden parts of automobiles outlast the 
car when treated with Reilly Transparent Penetrating Creosote. 


The permanence and safety of a home are assured by using lumber preserved with 

Reilly Transparent Penetrating Creosote for the sills, joists, 

sub-flooring, studding, roof timbers, uprights, and stringers. 

The house builder, by having his architect specify that only lumber 
treated with Reilly Transparent Penetrating Creosote shall be 
used in the construction of his building or home, is assured that his 
home will be a permanent structure and that IT WILL NOT BE 
tory owner, the automobile manufacturer, the furniture maker, and 
other users of wood are likewise assured of the permanence of the

wood in their products if the wood has been treated with Reilly 
Transparent Penetrating Creosote. 

Eradicates Termites 

The Reilly Tar and Chemical Corporation will supply special means 
and directions for the use of Reilly Transparent Penetrating 
Creosote to eliminate termites, powder-post beetles, and other insects 

Decay could not cause the destruction shown above if the lumber had been pre- 
served with Reilly Transparent Penetrating Creosote. All porch 
lumber should be made permanent by treatment with this preservative.

from buildings and lumber already infested by them. Not only does 
this preservative eliminate these destructive insects, but it also prevents 
their return to wood treated with it. 

Prophylactic Treatment 

If termites have not yet infested the building, or if the lumber is 
not yet infested with fungi, treatment of the lumber with Reilly 
Transparent Penetrating Creosoti will protect it against attack 

from both. 


A very unclean condition exists in the home when the wood is 

decaying and swarming with insects. The use of wood treated with 

REILLY Transparent Pi NetRating Creosotj assures the o^upant 

that his home will not be a breeding place of bugs nor will it be a bed

houses. All wooden structures which have not been properly preserved 
are subject to attack by them. And they even eat paper. They have 
fed upon such precious papers as "Jefferson's Manual on the Constitu- 
tion and the Rules of the House of Representatives." They have invaded 
the Bureau of Engraving and Printing, where they have eaten postage 
stamps and paper currency. 

Two distinct types of termites occur in this country, subterranean 
and non-subterranean. The former attack the wood from the ground; 
they even build tubes to feed on wood which is not in direct contact 
with the ground. The non-subterranean variety attack the wood directly 
after flying to it; this latter variety is sometimes referred to as the 
dry-wood termite because it attacks even the driest of timbers. 

Termite damage is always hidden inside the wood. The outside 
of the attacked wood may present a very sound appearance and it is 
only rarely that the presence of termites is detected before considerable 
damage has been done, and frequently not until the timber collapses.

For this reason it is far more economical to use Reilly Transparent 
Penetrating Creosote as a preventive instead of a curative meas- 
ure in combating termites. Lumber treated with Reilly Transparent 
Penetrating Creosote is assurance against the destructive action of 
these insects. 

Termites are not limited to any one section of the globe; they are 
found everywhere within the confines of the tropical, subtropical and 

Telegraph poles treated with Reilly Transparent Pene- 
trating Creosote are not destroyed by termites as was 
the one pictured above; neither do they decay. Poles so 
treated are dry, not oily, and can be painted.

temperate zones. About one thousand different species are known and 
it is estimated that as many as five thousand exist. The extent to which 

termite damage is spread over the United States is shown by the dark- 
ened portions of the accompanying map. 

The rapidity with which termites multiply makes them extremely 
dangerous. Originally these insects were found only in the tropical 
countries, but some got into the colder regions; most of these died, 
but a few of the fittest survived. These multiplied and in a short time 
a species was evolved which was adapted to a new climate. 


The rotting of wood is caused by a group of plants called fungi. 
These parasitic plants attach themselves to the wood, use it for food, 
and thus destroy it. 

Besides food, fungi require air, warmth and moisture for their 
growth. Conditions which normally prevail in buildings are such that 
the fungi have available all the essentials for their propagation. 

Misconceptions exist on the relationship of decay and the moisture 
content of the wood. An opinion seems to prevail that wood contain- 

Page Eleven 

ing less than 20', of water (based on the weight of oven-dry wood) 
will not rot. This is definitely wrong. The true dry-rot fungi, Merulius 
lacrymans and Porta hicrassata. which are responsible for a large 
amount of decay in buildings, bring about the decay of wood con- 
taining much less than 20% moisture. 

Wood absorbs moisture from the air. Even though the lumber 
has been air-seasoned or kiln-dried before being put into the building, 
it will not remain so under normal conditions. Paint does not water- 
proof lumber. It merely retards and does not stop the absorption of 
moisture by the wood. Thus even painted wood is susceptible to decay. 


The rotting of wood may be very rapid. It is not a slow process 
as is generally supposed. The entire frame of a factory building in- 
cluding many 8" x 18" oeams had to be replaced because of decay 
after three years of service. The accompanying photograph shows the 
extent of the destruction to a house done by decay in less than five years. 

Decay is spread to a considerable extent by direct contact of un- 
treated wood with infected wood. The fungus is in many cases intro- 
duced into a new building in the lumber itself. A piece of the new 
lumber has become infected in the lumber yard and then spreads the 
infection throughout the entire building. The possibility of receiving 
infected wood is entirely too great to be regarded lightly.

Decay fungi are also spread by the spores which they prQduce. These 
spores (seeds) are carried for long distances by the wind. If they 
settle on untreated or improperly treated wood, they sprout and germi- 
nate, and the wood commences to decay. 

This house was destroyed by decay in less than five years. The use of wood 

treated with Reilly Transparent Penetrating Creosotf 

assures against such destructive action. 

Fungus and insect attack in buildings are prevented by the use of 
Reilly Transparent Penetrating Creosote. It is easy to prevent 
decay in buildings, but it is a difficult matter to eliminate decay once it 
has started. To be assured that rot will not destroy a building, the 
builder need only specify that only wood treated with Reilly Trans- 
parent Penetrating Creosote be used in its construction.
